BlNNACLE-LAMP.

SPECIFICATION forming part of Letters Patent No. 309,960, dated December 30, 1884.

Application filed February 19, 1884. (No model.)

To ctZZ whom it may concern.-

Be it known that I, JOHN KEANE, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Binnacle-Lamp, of which the following is a specification.

The object of my invention is to provide an improved binnacle-lamp for ships, embodying ready means for adjustment, and so constructed that the light or rays of light will always be concentrated and deflected downward upon the compass-dial. I accomplish this object by the means illustrated in the accompanying drawings, forming part of this specification, and in which Figure l is a side elevation of my improved binnacle-lamp. Fig. 2 is a vertical sectional View of the same. Fig. 3 is a horizontal section taken on the oil-line, indicated by the dotted line Z Z, Fig. 2.

Similar letters of reference are used to indicate like parts throughout the several figures.

The body A of mylamp is constructed with a double cylinder, or so as to form an oiljacket around the wick-tube, oil feeder or fountain. The interior of this jacket is silvered, so as to concentrate and reflect the rays of light downward in the best possible manner.

The oil-fountain consists of a flat chamber, B, let into one side of and is an integral part of the oil-jacket. This chamber extends vertically from near the top of the oil-jacket to near the bottom thereof, so that the oil from the jacket will he regularly and constantly fed to the wick.

The oil-jacket, oil-chamber, and wick-tube may or may not be made in one piece, as de sired. If preferred, they can be made in separate pieces, and then brazed or soldered together; but the oil-passages should be perfectly free and open. The burner O is screwed to the top portion of this chamber, and to it is connected a key, D, which extends outwardly through the rim E at the top of the jacket, forming a thumb-ring, by which the wick of the lamp is raised or lowered. It is held in position by a pin, F, attached to a chain connected to the inside of the lampcase, as shown in Fig. 2.

Around the inner ledge formed by the top inspect at all times the state or volume of light through a tube, to be hereinafter more fully described. Draft-holes J are made at suitable intervals around the outer cylinder, and also below the oil-jacket. These latter holes, J, are covered from within by screenplates K, so as to prevent too great or violent a draft of air within thebody of the lamp. A thick, heavy glass bottom, L, set in a rim provided with two notches, fits into the lower end of the cylinder, and is locked in the usual way by bayonet-slots and pins to the said lower portion of the casing or cylinder.

The oil is fed to my lamp from the outside by means of a tube, M, which extends above the top of the oiljacket a sufficient distance so that the person filling the lamp can the.

more readily see when to shut off the supply. A cap or hood, N, shuts over the top of the lamp, and is firmly held by the pins and bayonet-slots O O, forming a close connection with the body of the lamp. The top of the hood is provided with a perforated chimney or cap, N, and within this is placed a metal screen, P, having holes of much less diameter than those in the chimney, and by this means downcast currents of air are prevented from entering the lamp with sufficient force to extinguish the light. An observation port-hole, Q, is made in the side of the cap, and a tube, R, inserted, at the end of which is a glass plate or lens, R, and the orifice is covered by a slide, S, as shown. Through this port-hole the volume of light is seen and regulated by the key before described. By this construction of lamp there is no possibility of extinguishment of the light even in the most violent gale; neither will it need to be trimmed While in the binnacle during the night.

In practice I place my lamp in the top of the binnacle, so that the lower end will come within a few inches of the compass, which causes a strong, steady, and concentrated light to be thrown directly upon the face of the com pass-dial at all times, and no light is thrown on deck to discominode the helinsman or offieer or watch.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. A binnacledamp formed of a double cylinder having an oil-space between the walls thereof, and an oil -chamber extending inwardly from said oil-space on one side, and integral therewith, by which oil is fed to the burner, substantially as shown and described.

2. In combination with a binnaclelamp having a double cylinder to form an oil-jacket, the interior surface of which is polished or silr ered to form a reflector, the truncated cone, cap, or chimney, also polished or silsilvered, and held in place by a projecting flange-plate and the wick-regulating key, in the manner as herein set forth and specified.

3. The wiclr-regulating key extending from the outside of the lamp, and provided with a collar, between which and the projecting
